Question

thr sum of 5% of a and 4% of b is 2/3 time the sum of 6% of a and 8% of b find the value of a/b​

Answer 1

Step-by-step explanation:

$5 \% \: of \: a \: + 4\% \: of \: b \\ = \frac{2}{3}( 6 \% \: of \: a \: + 8\% \: of \: b ) \\ \therefore \: 3(5a + 4b) = 2(6a + 8b) \\ \therefore \: 15a + 12b= 12a + 16b \\ \therefore \: 15a - 12a = 16b - 12b \\ \therefore \: 3a = 4b \\ \huge \fbox{ \therefore \: \frac{a}{b} = \frac{4}{3} }$
